"I never saw that coming, but it's so fun," he told Hoda Kotb and Kathie Lee Gifford of having children in his life. "At this point in my life, I kind of had put that, like -- 'Well, I guess that wasn't meant to be' -- and then all of a sudden it happens one way or another and it's like wow, I really missed out on a lot. So having them around is, I don't even know how to describe it, it's so much fun."

The couple has been dating since November 2015, and a source recently told ET that although the two appear more in love than ever, they aren't rushing to get married any time soon.

"There is no reason for them to rush into a marriage so they aren’t," the source said. "Both of them are happy and content with where their relationship is right now."

"They are on cloud nine for each other," the source added. "They are perfect for each other. They know they have found their true soulmate."
